Application filed April 11, 1916. Serial No. 90,431.

shoe which may be easily repaired by the wearer himself 'while in the field or on the road, without the assistance of an expert or professional shoe maker, the device being of such a simple character as to enable any one to quickly remove a half sole which is too far worn out for further use and to as quickly substitute therefor a new half 'sole and securely fasten the same in place.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, as herein described, illustrated and claimed. In the accompanyin drawings :-Figure 1 is a vertical longitu inal section through a shoe embodying the present invention. Fig. 2 is a vertical cross section through the same. Fig. 3 is a side elevation thereof. Fig. 4 is a 'plan view of the same. Fig. 5 is a bottom plan view of the open center marginal frame. Fig. 6 is a bottom plan view of the main sole. Fig. 7 is a detail perspective view of the retaining bridge for the half sole. Fig. 8 is the marginal frame of the half sole. Fig. 9 is a detail view of the toe cap. Fig. 10 is a detail view of the heel. Referring to the drawings, 1 designates an open center marginal frame which is composed of a thin strip of hard rolled metal so that it will have the necessary resiliency to keep its shape and retain the completed shoe in proper shape at all times. Projecting from the bottom face of the marginal frame 1 and arranged at suitable intervals entirely around and throughout the extent thereof are tubular bosses or projections .2 which are internally threaded to receive screws 3 of the machine type.

The main sole represented at 1 is also constructed of hard rolled or spring sheet metal and is provided along the margin thereof with holes 5 to receive the screws 3 above referred to. Extending in a transverse line across the bottom of the main sole 4 is another row or series of tubular bosses 6 which are alsointernally threaded to receive other screws similar to those 3 above referred to. 8 designates a half sole retaining bridge 1n the form of a metal strip extending transversely under the main sole and also under the rear edge of the half sole indicated at 9, the strip or retaining bridge 8 being provided at its opposite extremities with ears or extensions 10 which serve to space the main body of the bridge 8 at a distance from the bottom of the main sole 4 approximately equal to the thickness of the half sole 9, i

the cars 10 being fastened by screws at 11 to the frame 1, said screws passing through the appropriate holes 5 of the main sole 4.

The half sole 9 which is preferably composed of leather is fastened by means of ordinary tapering or wood screws 12 to a mar ginal frame 13 which is shaped to conform to the contour of the half sole and embodies the base flange 14: formed with holes 15 for the screws 12 and also an overhanging retaining flange 16 which is curved in cross section so as to embrace the edge of the main sole when the frame 13 is pushed in a rearward direction over the forward portion of the main sole. A toe cap 17 formed of pressed metal is adapted to fit over the toe of the shoe as shown in Fig. 3 and is formed with a base flange 18 having holes 19 to receive some of the screws 3 above referred to.

A hollow sheet metal heel 20 is provided around the top edge thereof with a flange 21 turned inwardly and formed with holes in line with the holes in the heel portion of the main sole and also provided with a flange 22 around the bottom edge, turned inwardly and provided with threaded holes to receive the heel lift fasteners. A metal heel lift 23 isformed to fit the bottom of the hollow heel and is provided with countersunk holes around its margin to receive the screws 34 by which said heel liftis fastened to the bottom of the heel, the holes 24 being in line with threaded holes in the bottom flange 22 of the hollow heel 20.

In assembling the parts hereinabove described, the frame 1 is'placed on the bottom of a properly formed last and the space within the frame 1 is then filled with an inner sole 25 of the same thickness as the frame 1 and the leather or other suitable material to provide a smooth interior for the completed shoe. The upper indicated usual manner employed by shoe makers and holes or incisions made in the leather to adapt the same to fit over the projections or bosses 2. A gasket 27 of rubber or like material is then placed over the inturned edge of the upper and prevents the admission of water or moisture by being inserted between the upper and the sole. The main sole 4 is then placed in position and screwed down tightly by means of the screws 3. The toe cap 17 and the heel 20 are fastened in place by the same screws thus completing the shoe with the exception of the wearing parts thereof consisting of the half sole and the bottom lift of the heel.

The frame 13 carrying the half sole is slipped over the front portion of the' main sole before the toe cap 17 is fastened in place and lastly screws are inserted through the retaining bridge 8 into the rear edge portion of the half sole 9 thus completing the shoe. In order to replace an old half sole with a new one, it is only necessary to unscrew the bridge 8 or remove the screws thereof and also unscrew the toe cap, whereupon the old half sole may be slipped off the forward portion of the main sole. A new half sole is then fitted to and fastened in the frame 13 and the latter is slipped over the forward portion of the main sole so that the flange 16 thereof will embrace the edge of the sole. Then the toe cap is replaced and secured and the rear edge of the main sole is fastened under the retaining bridge 8 in the manner described. The ears or extensions 10 when firmly screwed to the main sole, remove the strain from the screws holding said plate to the sole and hold the half sole firmly in place. It will be observed that there are no screw holes formed so as to admit water to the interior of the shoe as nearly all of the screws are of the machine type, and internally threaded bosses or projections are provided to receive said screws. The ordinary wood screws 12 referred to are embedded in the half sole and therefore cause no leakage.

It is, of course, intended to carry an ample supply of extra soldiers on the march or 1n the field so that a new sole and heel lift may be substituted whenever necessary and also a new half sole frame 13. In view of the construction hereinabove described, the material may be made lighter than the leather used in the ordinary working shoes or shoes of a heavy type and therefore the improved shoe will be lighter on the foot and furthermore will not alter its shape on account of the nature of the material used, particularly the frame 1, the main sole 4 and the frame 13 which holds the half sole in place. This insures a comfortable shoe which will render walk- 111g easier. It is furthermore water tight arts in case of and is not subject to serious injury in case the sole of the shoe is held close to a stove or fire in order to dry out the same.

For army purposes, the shoe will be especially valuable while marching or in the field as it will not be necessary to carry a large stock of shoes but only the portions thereof which are subject to the greatest wear and these may be packed in a comparatively small space. The toe cap serves the double purpose of fastening the half sole frame more securely to the main sole and also to prevent the toe of the upper from becoming damaged by stumbling against unseen objects. Furthermore, no sharp objects such as iron or wooden pegs may penetrate the main sole by reason of the fact that the latter is formed of metal. The only tool necessary to repair the shoe is a screw driver. The materials employed render the shoe cheaper to produce than the ordinary common leather shoe and the cost of repair is very much in favor of the shoe hereinabove described, requiring no paid-labor as the wearer himself may make the necessaiiy repairs.

aving thus described my invention, I claim 1. In a shoe, an open center marginal frame provided on the under side thereof with internally threaded tubular bosses arranged at intervals throughout the length of said frame,

a sheet metal main sole provided with holes bridge extending transversely of the main sole and secured at its opposite extremities thereto and formed with holes in line with the last named internally threaded bosses, a half sole marginal frame provided with holes in line with corresponding holes in the main sole, a half sole fastened in the last named marginal frame, and screws inserted through said retaining bridge into the rear edge portion of said half sole.
